Have you had any belts changed recently?

An over tightened belt can cause a whirry/whining noise, in my case we over tightened my new cam belt

[johnboy2124]

i only had the car 4 weeks and the belt does look new ! so not sure how to check if its to tight !!

how do i check if its to tight and how to release it if it is tight ?" ??

[johnboy2124]

are these belts self adjusting ??? as i asked my mate he thinks they are and probably wouldnt cause that whiny noise ?!

any other helpful hints tips ???

Yeah they are self tensiong actually, well the aux belt is, not the cambelt!

Did this whine occur pre-new starter motor?

[johnboy2124]

yes it was whiney before new stater motor !! ?

i hope its not the cam belt !!!!!!! guy said he had it done !

The cambelt isnt self adjusting, the tensioner is set manually!

Im only talkin from experience here but when i did mine a bit too tight it made a whiney noise!
